Function Manual, 09/2011, 6FC5397-2BP40-2BA0
Meaning
Generator operation (Vdc controller)
Meaning
When reaching the lower DC link voltage threshold (p1248) – for ESR – the
motor is braked in order to utilize its kinetic energy to buffer the DC link.
Description
Lower DC link voltage threshold
Setting the lower threshold for the DC link voltage. For p1240 = 2, this threshold is
used as setpoint limit for the Vdc_min controller.
Upper DC link voltage threshold
Lower DC link voltage threshold
Rated power unit line supply voltage.
The pulses are canceled if the DC link voltage drops below 0.9*r0208
